Abstract Xingyu Coal Industry of Shanxi Lu'an Group is an integrated mine with dozens of small mining goaf areas around the mining field, which is seriously threatened by goaf water. In order to achieve safe recovery, based on the analysis of its hydrogeological conditions, the water-rich coefficient comparison method and the groundwater dynamics method were used to predict the mine's water influx, and the goaf water was evacuated using measures such as drilling and releasing, water interception alley, slurry plugging and water drainage alley. The practice showed that the amount of water in the workings after sparing was small, achieving safe recovery and a better control effect.
